Well, what happens when the theater starts running ads? CNN reports that, following a pilot program at LAX, the TSA is getting ready to sell ad space in those ubiquitous gray X-ray trays in order to raise revenue. Is it right for a government agency to foist advertisements on a captive audience? And once the TSA becomes dependent on ad revenue, will it get that much harder to convince them to roll back ineffective procedures?"
